Patented Dec. 17, 1929 UNITED STATES ArsNr OFFICE WALTHER EASTER, OF CHICAGO, ILLINOIS, .ASSIGNOB '10 JUSTRITE MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS LAMP-ATTACHING DEVICE FOR MINEBS CAPS Application filed December 12, 1927. Serial No 239,406.

The invention has for its object to provide an attachment for a miners cap for cooperation with a fitting on a lamp to be attached to the cap which will permit the lamp to be readily attached to and detached from the cap; will provide means whereby the lamp is held firmly in place on the cap when attached thereto and which will obviate discomfort to the wearer of the cap by reason of the presence, as heretofore, of a projection so positioned as to occasion discomfort to the wearer of the cap when the lamp is attached thereto.

A further object of the invention is to provide an attachment for the cap which, in sale, constitutes a detachable part of the lamp and may be easily mounted on the cap by the purchaser.

The invention, while preferably embodied in an attachment of the type indicated in the last preceding paragraph, may also be embodied in an attachment which may be incorporated by the manufacturer of the cap as a permanent, non-detachable elementof the latter to receive lamps equipped with the companion element.

In the accompanying drawings illustrating the invention:

Figurel is a fragmentary vertical section of a-miners cap equipped with a lamp carrying attachment constructed in accordance wlth the invention.

Figure 10 is a sectional view similar to Figure 8 illustrating a modified form of construction.

v Figure 11 is a view similar to Figure 5 showing the lamp body equipped'with a device for coaction with the structure shown in Figure 10.

The lamp supporting member 1 of the cap 2 consists, usually, of sheet metal and fibre board. 7 This membercomprises a middle portion and two oppositely extending end flanges 3 and f, one of which is rigidly secured to the visor 5 of the cap and the other to. the crown. The sheet metal is usually very thin and is provided with side flanges 6 which are folded in part to lie upon the body portion and in part to secure apiece of fibre board to the middle-portion of said member, said portion being provided with a relatively large opening 7 near the upper end thereof and with a slot 8 which intersects the bend at the inner end ofthe flange a. 1

Lamps, such as the acetylene type, have been provided with hooks to engage in'the slots 8 and, 'insome;instances, with'spring clamps for engaging the side edges of the middle portions of the members'l, and, by reason of the fact that the hooks are relatively large, the points thereof are apt to press against the foreheads of wearers of the caps and are annoying. The aforesaid means for attaching the lamps are also deficient in that the lamps are'not very firmly held in place thereby. i

The present invention is designed to overcome the defects and objections incident to the substantially conventional attaching means now commonly used as above described 7 and, in order that the attaching means may be applied to existing caps, an important element of the present invention lies in provid ing means which are adapted for association with the lamp supporting member of the cap by the purchaser of. the lamp and its companion carrier.

The lamp carrier shownin Figures 1 to V minatesat itsupperend in the flange 12 which overhangs but is spaced from theflange 4 of the member 1. The said portion 9 and flange 12 are provided'attheir side edges with the tongues 18 and 14, respectively, which are slightly offset therefrom,the free end portions of said tongues being easily bent, digit ally, about the side edges of the member 1 and its flange 4, respectively, and are shown so bent in the drawings, but, when delivered to the consumer, are straight. The tongues 13 and 14 cooperate with each other and the portions of the member l-engaged thereby to very firmly secure the member 9 to the member 1 while maintaining the former oflset from the latter. This is rendered necessary in instances where the members'l ofcaps are equlpped with certain recently introduced {devices for attachingelectric lamps to the caps.

The free portions of the guide flanges 11 are not quite as long as the slot 10 but are cut away in part to provide guide ribs 15 which are slightly convergent.

The lamp body 16 is provided at the back with a'pair of guide flanges 17 which, preferably, constitute inturned side edge portionsof a plate 18 secured to the lamp body 16 and are spaced and arranged so that their free portions will engage under-the free portions of the flanges 11 to provide a snug fit. The guide ribs 15 are adapted to act as leads'to enable the wearer of the cap to moreeasily associatethe lampwi'th the member 9. The length-of the lamp is such thatwhen attached to the mem ber 9 its bottom rests upon the flange 3 of the member '1 as shown in Figure 1, said flange .thus providing a stop formation cooperating with the flanges 11 to hold the lamp in place.

The embodiment shown in'Figure 6 differs from that shown in Figures 1 to 4 inclusive- "-111 that the pOTtIOHS-Of the tongues which, in

Figures 1 to 4 are shown ibent about the side edges of the member 1 and its flange 4, are omitted, the terminals of said tongues 19 be ing clamped between the member 1 and its flange 4 and the side :flanges =6 folded-over upon said parts, this form o-fembodiment bei-ng adapted to be supplied to the manufacturer of the caps for incorporation into the same. I

It will be obvious that the function of the-flange 12'0f the member '9 and'the tongues 14 thereof, is to hold said member 9 against longitudinal movement relatively to the member 1. In Figures 7 and'9, Ihave shown an embodiment-wherein said flange 12 and tongues 14 are omitted. In this embodiment I employ a plate 20 having tongues 21 the terminals of which are bent or folded over the side edges of the member 1 to hold the plate 20 against lateral movement. In the latter I provide a central opening 22 which is bordered by an annular flange 23 which engages in the opening 7 of the member 1 to holdtheplate 20 against longitudinal .movement relatively to the member .1.

Integral with the plate 20 is a flange 24 which isprovided with the slot 25, side flanges 26 and guide ribs 27 which correspond to the slot 10, flanges 11. and. guide ribs 15, respec tively, of the embodiment shown in Figures 1 to 4 inclusive. The flange 24 is bent between its ends as at the point28to extend'substantially parallel with the plate 20, thelatter being further provided at its lowerrend with a flange 29 which is foldedover upon the lower end-of the flange 24 forobvious reasons.

It will be obvious also, without specific illustration, that the structure of Figures 7 and 9 may be modified .by cutting away "the terminal portions ofthe tongues 21 extending over the side'edges of the member 1 andthe edges of the shorter tongues confined between the member 1 and its side flanges .6 as in the embodiment shown in Figures 6 and 8.

In theen'ibodiment shown in Figures 10 and 11, which concerns only the interengaging flanges on the lamp and its carrier, the carrier 30 is shown as being of the type of Figures 1 to 4 inclusive and is provided with the slot 31 corresponding to the slot 10 of Figures 1 to 4, said slot being bordered by the L-shaped fianges32 the free or outer portions of which project over .the side'portions of said slot 31,

the lamp body being provided .with outward ly extending flanges 33 :for interengagement' with said flanges '32.

The assembled structure of Figures 1 to 4 and that of each of the remaining figures showing other or modified embodiments, is,

broadly, in each instance the substantialequivalent of a lamp supporting member equipped with lamp engaging means integral with ,-or permanently associated therewith, it

being obvious that ordinary skill in me chanics will sufliceto enable the artisan to so supporting device in any direction, a .lamp,-

and interengagin'g devices on said lamp and. said sheet-metal member for detachably associating the latter with said lamp.

2 Means for detachably associating a I 5 lamp with a miners cap equipped. with a conventional lamp supporting device, comprising a sheet-metal member equipped with ele ments engaged with the said supporting device for holding said member against lateral and longitudinal movement thereon, a pair of parallel substantially vertically disposed guide members on said sheet-metal member, a lamp, and a pair of similar guide members on said lamp arranged for sliding engagement with the guide members on the sheet-metal member for detachably interlocking said lamp with the latter.

3. Means for detachably securing a miners lamp to a conventional miners cap equipped with a flat substantially Z-shaped device secured at one end portion to the visor and at its other end portion to the crown of said cap, said means comprising a substantially L- shaped fiat sheet-metal member equipped at 5 opposite end portions along its side edge with tongues folded over the side edges of the middle portion of said device, there being an elon 4 gated slot midway between the side edges of that portion of said member opposing the middle portion of said device, L-shaped flanges bordering the sides of the slot and converging toward each other at one end of said slot, and a member rigidly mounted on the lamp equipped with similarly spaced and converging L-shaped flanges for engaging the flanges of the said member for firmly and detachably associating the lamp with the cap.
